While playing in Shuangyashan, Heilongjiang province… Pierce and Beasley both suffered asthma attacks due to large amounts of fans smoking cigarettes inside the stadium. After the game, things got even more shocking when Beasley fell to the floor in his hotel and started to roll around in obvious pain, scaring everyone around half-to-death. At that point, there was no choice but to dial 120 (the number for an ambulance in China) and take him to the hospital.

We think they're conflating the hospital visit with his wrist injury the next day, but there's no doubt the smoke was a factor. On their blog, an Australian team taking part in the tourney noted the playing conditions were less than ideal:

Once again tonight we arrived to a smoke hazed packed stadium, it appears the "dangers of smoking memo" is yet to make its way to the Far East.
